Hi

Ok, it's a dumb question but I really don't know the answer...

Can a VGA PCI E 2.0/2.1 run in a PCI E 3.0 slot?

Thank you!

Yes, but PCIE 3.0/2.0/2.1 cards sometimes don't work with PCIE 1.0/1.1 slots unless the manufacturer provide a BIOS update support this.

Hmm ok then.

I have a VGA PCI E 2.1 in a PCI E 2.0 slot.
I think it's performance wasn't maximised.

Will it be at PCI E 3.0, right?

Video cards do not fully fill up the bandwith of the Pci-e 2.0 slot or the Pci-e 2.1 slot so yes your card is maximized and it doesn't need the Pci-e 3.0 slot.

Yes it. PCIE 2.1 is the same as PCIE 2.0

PCI Express 2.1 supports a large proportion of the management, support, and troubleshooting systems planned for full implementation in PCI Express 3.0. However, the speed is the same as PCI Express 2.0.
